Sildenafil, the active ingredient in Viagra, primarily treats erectile dysfunction (ED). It works by increasing blood flow to the penis, facilitating an erection.
Beyond ED, sildenafil also treats pulmonary arterial hypertension (PAH), a condition causing high blood pressure in the arteries leading to the lungs. This application relies on its ability to relax blood vessels.
- Erectile Dysfunction: Sildenafil helps men achieve and maintain erections sufficient for satisfactory sexual intercourse. It’s taken as needed, usually about 30-60 minutes before sexual activity. Dosage varies, and a doctor should determine the appropriate amount. Pulmonary Arterial Hypertension: For PAH, sildenafil is taken regularly as prescribed by a physician. It helps improve exercise capacity and reduce symptoms like shortness of breath.
Important Considerations:
Consult your doctor before using sildenafil, especially if you have heart problems, low blood pressure, or take other medications. Potential interactions exist with nitrates and some other drugs. Side effects, while generally mild, can include headache, flushing, nasal congestion, and visual disturbances. Severe side effects are rare but require immediate medical attention. Sildenafil is not a performance enhancer; it only assists with erectile function for men who already have some degree of sexual stimulation.
Always follow your doctor’s instructions and seek their advice for any questions or concerns regarding sildenafil use. Do not exceed the recommended dosage.
